Data sheet acquired from Harris Semiconductor

SCHS099B â Revised January 2003

The CD40109, unlike other low-to-high

level-shifting circuits, does not require the

presence of the high-voltage supply (VDD)

before the application of either the

low-voltage supply (VCC) or the input

signals. There are no restrictions on the

sequence of application of VDD, VCC, or the

input signals. In addition, with one

exception there are no restrictions on the

relative magnitudes of the supply voltages

or input signals within the device maximum

ratings, provided that the input signal

swings between VSS and at least 0.7 VCC;

VCC may exceed VDD, and input signals may

exceed VCC and VDD. When operated in the

mode VCC > VDD, the CD40109 will operate

as a high-to-low level-shifter.

The CD40109B-Series types are supplied in

16-lead ceramic dual-in-line packages

(F3A suffix), 16-lead dual-in-line plastic

packages (E suffix), 16-lead small-outline

packages (NSR suffix), and 16-lead thin shrink

small-outline packages (PW and PWR suffixes).
